Pixel 10 is operated by including the drive circuit (" image element circuit ") of driving transistor and luminescent device.Hereinafter, pixel 10 can refer to image element circuit.Luminescent device can be arbitrary Organic Light Emitting Diode, but the image element circuit implementing to be applicable to include there is other electroluminescent device of current drive-type luminescent device of the present invention.Driving transistor in pixel 10 can be arbitrary n-type thin film transistor or p-type thin film transistor, but the enforcement of the present invention is not limited to have the image element circuit of the transistor of particular polarity or have the image element circuit of thin film transistor (TFT).
Pixel 10 is connected with selecting line the 122, first supply lines the 142, second supply lines 144, data wire 114 and monitoring line 112.Pixel 10 selects line 122 to be provided by address driver 120, and can be used to such as be allowed for by activation switch or transistor the programming operation of pixel 10, so that can be programmed by data wire 114.Programming information is transferred to pixel 10 from data driver 110 by data wire 114.Such as, program voltage or program current are applied to pixel 10 by availability data line 114.Program voltage/electric current is at such grade: such grade is enough to the capacitor in pixel 10 is charged such that the electric current to driving transistor to be operated flowing through luminescent device with transmission, thus to have the Intensity LEDs of desired amount of brightness.The program voltage (program current) supplied by data driver 110 by data wire 114 is usually by the relation represented with formula and/or by digital data value mapping to the look-up table of program voltage/current class and relevant to the numerical data that controller 130 receives.

IRDrop " and " IRRise " refers to the voltage caused by resistive circuit loss, and " I " refers to the electric current on circuit here, and " R " refers to line resistance.The voltage putting on luminescent device (selectively, it is possible to be OLED) is shown as VOLED。VOLEDValue generally depend on the characteristic of luminescent device 154, the aging history of luminescent device 154 and/or the electric current flowing through luminescent device 154 and being transmitted.In some instances, VOLEDValue can along with increase large-drive-current (such as, the brightness increased) and increase, and can by it be compensated by above-mentioned increase measurement and/or prediction, above-mentioned measurement and/or prediction are measuring or carrying out for the aging deterioration (agingdegradation) of prediction is mapped to the standardization look-up table of use history/log file based on what store in memorizer 116 according to monitoring system 115.
Put on and drive the voltage of transistor 152 to be illustrated as VDS, V hereDSCan refer to put on " Drain-Source " voltage driving transistor 152.In certain embodiments, magnitude of voltage (such as, the dram-source voltage V of transistor is put onDS) enough make driving transistor 152 be maintained at the saturation mode of operation, because the amount of the electric current being transmitted through transistor when saturated is basically independent on the voltage putting on transistor.Such as, V is worked asDS>VGSDuring Vth, drive transistor 152 can operate in saturation mode, V hereGSBeing drive the voltage between the gate terminal of transistor 152 and source terminal, Vth is the threshold voltage driving transistor 152.Therefore, transistor 152 will be driven to be maintained at the V needed for saturation modeDSValue depend on VGSValue and threshold voltage Vth.Owing to driving the current weigher of transistor 152, the value of Vth is likely to time to time change.It is similar to above for VOLEDDiscussion, in time the value of Vth can be compensated according to based on such as monitoring the measurement that system 115 carries out and/or measured value and/or the predictive value being stored in look-up table that is in memorizer 116 and that map to use record/history.At VDSValue more than by when driving transistor 152 to be set in saturation mode required value, overvoltage (that is, is still applied to drive the V of transistor 152DSPlussage) usually used as thermal dissipation drive transistor 152 channel region in.In some instances, heat production too much in channel region can disadvantageously result in the deterioration driving transistor 152, and therefore causes the aging of display system 100.
Therefore, in some instances, Vdd is selectedsupplyAnd/or VsssupplyValue with provide put on drive transistor 152 be enough to will drive transistor 152 voltage (such as, the voltage V that is set in saturation modeDS).Based in part on VddIRDrop, VssIRRise, VOLEDV is determined with the measured value of Vth and/or predictive valueDSDesirable value.Additionally or alternatively, because programming information affects VGSValue because the brightness of luminescent device 154 is generally with to flow through the electric current driving transistor 152 relevant, and the electric current flowing through driving transistor 152 is subject to V at least in partGSRegulate, so determining V based in part on the programming information for image element circuitDSDesirable value.Such as, can according to relations IDS=β (VGSVth)2Set and flow through the electric current (" I driving transistorDS"), β characterizes the variable of the I-E characteristic driving transistor 152 and can include driving the grid oxic horizon of transistor 152, aspect ratio and mobility etc. here.Therefore, V is determined based in part on the brightness exported from image element circuitGSValue, and therefore determine V based in part on the programming information for image element circuitGSValue.
